Andre Ayew has rejoined Swansea City in a club record £18million deal.
The Ghana international will link-up with his younger brother Jordan after agreeing a three-and-a-half year deal.
Ayew scored 12 goals in his previous spell at the Liberty Stadium, helping the Swans avoid relegation after a disappointing start to the season.
The 28-year-old then left for the Hammers in a £20.5m deal 18 months ago scoring 12 goals in 50 games.
Ayew’s task will be again helping the Swans survive in the top flight with boss Carlos Carvalhal confident he can boost his forward line.
The former Marseille striker’s fee beats the club record £16m paid for midfielder Sam Clucas last summer.
Ayew’s move was finally agreed after the Hammers signed Jordan Hugill from Preston.
Swans midfielder Ki Sung-Yueng had been linked with a move in the opposite direction as part of the package, but the South Korean wanted to stay in South Wales.
